7 1 Claim.

My invention relates to light sockets and securing means therefor and has for its principal object to dispense with the nipples and other mounting devices usually required, thereby simplifying and cheapening the structure. The invention consists principally in dispensing with such nipples and other securing means and in securing the light socket directly to the reflector member. The invention further consists in the light socket and securing means therefor and in the parts and combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawing,

Fig. 1 is a top plan view of a reflector member in which is a light socket secured by light socket securing means embodying my invention,

Fig. 2 is a front elevation thereof,

Fig. 3 is a sectional view on the line 33 of Fig. 1,

Fig. 4 is a sectional view through the light socket on the line- 4-4 of Fig. 1,

Fig. 5 is a plan view of the body of a socket member having a detachable porcelain cover and also a plan view of the inside of said porcelain cover, and

Fig. 6 is a view showing a socket member of different type secured in position by light socket securing means embodying my invention.

Figs. 1 to 5 illustrate a display light construction that includes a troughed reflector member 1 that is mounted in any desired display case or the like. The drawing discloses one of a number of electric light socket members 2 mounted in said reflector 1, Figs. 1 to 5 illustrating a porcelain socket member split longitudinally to form a separate removable cap portion 3.

The present invention involves changing the structure of the light socket member itself so as to avoid the necessity for using nipples and other complicated securing devices for mounting the socket member in the reflector. The socket member 2 is provided with a pair of transversely extending bores or passageways 4 in which are mounted metal sleeve portions 5 that are interiorly threaded to receive screws 6, said screws extending through holes 7 provided therefor in the reflector member 1. Between said screw bores 4, the socket member is provided with an enlarged transverse passageway 7 adapted to receive the wires 8 for the socket member 2, the reflector member 1 likewise being provided with a hole 9 through which said wires 8 pass. Preferably, said hole 9 in the reflector member is large enough to receive an annular rib 10 or projection on the under surface of the socket member surrounding the end of said wiring passageway '7, whereby the socket member may be easily centered in the reflector member and the securing screws 6 positioned. The body of the socket 2 is shaped to fit the reflector member 1 throughout a considerable portion of its surface.

In practice the body of the socket member may be secured in the reflector and the wires 8 passed through the passageway 7 of the socket member and their ends attached to the terminal screws 11 of the socket member. After the wiring has been connected up and inspected, the removable cap portions 3 of the sockets may be positioned.

Fig. 6 illustrates the same securing means applied to a socket member 31 of different construction, such socket member including a metal cap member 32 at one end, said cap member being flattened to fit the reflector member 1 and having threaded holes 33 adapted to receive securing screws 34.

The above described construction greatly facilitates the operation of assembling socket members in display light constructions and reduces the expense thereof. Obviously numerous changes may be made Without departing from the invention and I do not wish to be limited to the precise construction shown.

WhatI claim is:

An electric light socket member, a mounting therefor, said socket member having an enlarged transverse passageway adapted to receive wiring and terminals for said wiring, a cap for said socket member covering said terminals, said socket member having threaded bores on either side of said wiring passageway, said mounting having holes alining with said threaded bores and having an enlarged opening alining with said Wiring passageway, screws passing through said mounting holes into said threaded bores and a screw extending through said cap into one of said bores.
